Where at the 39/19? or when you were trying to reduce 21/19
Answer:
Yes.. you are correct!
Step-by-step explanation:
Please give me brainliest.
We know that:
<span>rate = 0.15 heaters /labor hour</span>
labourer time = 160 hours /
month
goal = 57,600 heaters / year
We can solve this problem by
simply looking at which ratios will cancel out the units:
<span>number of labourers = (57,600
heaters/year) / [(0.15 heaters /labor hour) * (160 hours/month) * (12 month/year)</span>
<span>number of labourers = 200</span>
Answer:
5x² - 20x
Step-by-step explanation:
multiply each term in the parenthesis by the 5x outside
5x(x - 4)
= (5x × x ) + (5x × - 4 )
= 5x² + (- 20x) = 5x² - 20x
